Application filed November 3, 1911. Serial No. 658,335.

lie it known that il, MAX (leuning, a subject of the lhnperor of Germany, residing at Berlin, Germany, have invented certain new and useful lmprovements in BalLBearfollowing is a specification, reference being had therein to 'the accompanying drawing.

This invention relates to separators or M cages for anti-friction bearings, for mainsame time fasten the parts of the 'of fastening taining the rolling elements in spaced relations, and the invent-ion has reference more particularly to that type of 'cage comprising opposing sections, commonly in the form ofv rings, which are provided in their adjacent faces. with recesses constituting conjointly holding sockets for the rolling clemente, the said rings being connected to gether byA suitable fastening devices.

'1 The object of the present invention is to so L'asten the parts of the cage. together that they will be securely and firmly united, while at the same time admitting of the employment of the greatest number of rolling elements.

A fulli connilement` of rolling elementsnecessitates that they be arranged -very close together in the cage with their surfaces just out of contact. When thus arranged, the portions of the cage between the rolling elements are very limited and not of such extent orv width to admit of the employment devices of sn'licient size beA tween the rolling elements to properly and securely hold the parts of the cage together.

n order to admit of the full equipment of rolling elements in the cage and at the cage firmly and securely together, l propose in accordance with my invention to apply to the parts the cage, a casing or sheath which will have an extended contact with the cage tions, and propose to einl'iloyfastening devices` for clamping the casing to the cage sections. As a result of this construction, the fastening devices may be of such a size and form which will-admit of their use between the closely assembled rolling elements.

.but which` will on account of the external nientary rings or sections provided in their `outer edges at points betweenthe balls with open slots, which rings are inclosed within @the sections of the casing and fastened together by 'clamping or fastening devices eX- tending through the parts of the casing and into the slots in the cage sections, and engagingwit'h the casing in such manner as to firmly and securely hold the sections of the same together. lt is manifest, however, that the invention in its broader aspects is susceptible. of other forms of embodiment, and is not limited to any particular form or construction of the parts except in so far as such limitations are set forth in 'the claims. In the accompanying drawings: Figure l isa plan view of the inner face of one of the complementary sections of the cage and the inclosing casing section, embodying my invention and showing the balls seated therein. Fig. 2 a sectional elevation of the complete cage, the section beingr taken on a line extending diametrically across the center of the same. Fig. 3 is a` plan view of a half portion of the same. Figs. el to 7 are each plan and sectional views respectively, show? ing different forms of the fastening devices for Securing the parts of the easing together.

Referring to Figs. l, 9. and 3, my improved cage comprises its essential features, in one form of embodiment, two complementary ring-like sections l and 2, re-v cessed in their adjacent faces to constitute ball holding sockets, a sheath or casingnl embracing and inclosing the sections of the cage, and a series of fastening devices 4 applied to the casing and serving to clamp the same in the parts of the inclosed cage.4

The recesses in the cage sections are so spaced that the balls A seated inthe sockets formed thereby, will be disposed in very close arrangement, their surfaces 'being just out ot' contact with eachv other, so that the maximum number or the full complement. of balls may be employed. At intervals in their outer edges, corresponding in position to the intervals between the halls. the sections of the cage arc formed with open slots .5, 5, etc., extending axially thereof, as shown in `Figs. `l and Q, the purpose of whiclnwill presently appear.

The casing?) is preferably in two complementary sections 3 and 3b, Usshape in cross section, so as each to fit over and embrace one of the sections of the cage, these casing sections constituting conjointly an int-,losing section.

applied at intervals throughout the circumsheath or casing for the cage, as shown morev 'of which are passedv through openings "formed at intervals in the casing sections corresponding to the position of the open slots in the cage sections, the ends of said limbs being bent inwardly toward each other as at Il and seated in the circnmei-,

'ential groove in yone of the casing sections, while the head of the staple' is seated in the circiunerential groove of theothercasing TWith the' fastening devices thus ference of the, cage, the parts of the casing will be firmly fastened together, and by rea son of the eiitended contact of the casing with the cage sections inclosed therein, the latter willbe held lirinlymandv ixedly together and without liability oi accidental separation. The exposed `portions of the fastening devices being seated in the grooves in the casing sections, the cage .will be free from projectingparts and there will be no liability of the ends ofthe staples being bent outwardly accidentally when the cage is inuse.

'ln Fig. Il the construction'is the same as thatl just described, except that in securing kthe clamping devices, after being placed in position, the projecting ends of the same are bent outwardly in opposite directions from each other, as at 4. ln the construction shown in Fig. 5,A the fastening devices are, as in the first instance described, in the form of U-shaped staples, but with the addition of arms 4 on the ends of the limbs, -which arms are extended inwardly toward the inner edge of the cage and seated in radial lgrooves Se forined in one of the casing,` sections, the ends ol the arins being bent down laround the inner edge of the casing, as at 41E, to secure the staples in place.

n Fig. 6 the construction is the same its in Fig. 5, except that the ends of the arms 4d are extended through the side of one of the casing sections and into the cage, as at Alf,

mental ln Fig. 7, the circumferential grooves in the casing sections are omitted, and the fas toning devices consist each of a single limb or body portion 4g, extending through the se two parts of the casing and seated in. the operi slots in the cage sections, the ends of the limbs being provided with inwardly extendingarms Ll lseated in radial grooves 3f in the casing sections, and having their o5 treniities extending inwardly through the sideof the casing sections and into the cage'- sections.

Having thus described my invention, what lf claim is: le

l. A cage :tor antifriction bearings coniprising two annular sections recessed in their adjacent faces to constitute holding sockets for the rolling elements, and provided in their external edges with open clin lo ing lslosla two-part -casing applied to the cage sections and provided with external grooves, and fastening staples having-their body portions extending axially .thi-wh the casing/sections and engaging'infthe slots es in the1 cage sections', with the'le"y portiions of said staples embedded inthe grooves in the casing sections, said fastening staples serving to bind the parts together in an axial directionon the balls, and acting to 85 prevent the relative circumferential .displacement of the cage sections and casing sections. l l

2. A. cage for antii'rictio'h bearings. coniprising tn'io annular sections recessed in their adjacent faces to constitute holding ockets for the rolling elements, and provided in their external edges with open alining slots, a two-part casing applied tothe cage sections and provided with external s circumferential grooves, and fastening staples having their body portions extending axially through the casing sections andl en- 4 gagging-,in the slots in the cage, with the leg portions ci' said staples embedded in the cirn .cnniferential grooves in the casing sections,

said 'fastening staples serving 'to bind the parts tegetherin an axial direction on the balls, and to prevent the relative displace ment of the cagesections and casing secl' tions. .v

ln testimony whereof l ailix my signature in presence ci two witnesses.
